Immediate coupling between servo electric motor and worm gear is among the key strengths of EP worm gearmotors, which combine DC motor technology with exceptional durability and wear resistance. Electric motor and gearbox are designed as one single, compact unit. Because of their reduced current draw, these gearmotors deliver more accurate control of operating temperature and higher performance.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear business lead screw / ball screw adapted to your flexible modular concept.
Based upon this we are able to select a wide variety of standard customizations to meet the requirements of various properties that are important for each application.
If your application requires a gearbox with some special real estate such as for example small dimensions or low weight with regards to power, high efficiency, quiet and vibration-free operation, extended life, high resistance to vibration, pressure or temperature, integrated linear screw, or a combination of such properties, our item range with an increase of than 1000 different standard gearboxes is most likely a good begin to have the ability to deliver something that stands out on your side.
Compact gearboxes are high-quality gearboxes for standard drives. The electric electric motor is built-in with the gearbox into a single device (the first gear is directly on the electric motor shaft). Separate gearboxes for link with conventional IEC motors can also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our experts will be pleased to help you create your selection. We are happy to send you documentation or style a suitable set directly, on request.

Ever-Power worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-artwork technology, all and will be offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low quickness gear ratio. Being basic and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type qualities act like helical gears, but its helix position is typically comparatively bigger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key components for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear devices are built to withstand the toughest industrial applications.
The gear housings are machined on all sides and permit diverse mounting positions and applications, producing them much sought after in the industry. Because of this our geared motors are often to be found within our customers own machines.
The smooth running of Ever-Power gear units and the outstanding load capacity of WATT teeth are achieved with 3D design backed by FEM (Finite Element Method). This tooth geometry ensures optimum rolling contact under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity enables smaller tires to be utilized for the same torque, and smaller gears with outstanding power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing perform required for troublefree rolling contact to be substantially reduced and then the gear backlash to end up being minimized.
Dual chamber shaft seals developed by Ever-Power are used as standard in parallel shaft, shaft mounted and helical worm gears for a high level of tightness.
Ever-Power’s modular equipment technology meets certain requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
